8y - y + 12 = 61
7y + 12 = 61
7y = 61 - 12

The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20
Pepsi [2]

Answer: They can order from 0 to 449 bars, but no more.

Step-by-step explanation:

Given: The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20.00 for shipping regardless of the size of the order. The band must spend less than $200.00 on bars for the fundraiser.

The inequality below relates x, the number of bars that could be ordered, with the shipping costs and their spending requirements.

0.40x+20

To solve for x,  subtract 20 on both sides, we get

0.40x

Divide 0.40 on both sides, we get

x......... → the number of  bars that could be ordered, with the shipping costs and their spending requirements must less than 450.

Thus, they can order from 0 to 449 bars, but no more.

If s(x) = 2 – x2 and t(x) = 3x, which value is equivalent to (s t)(-7)? A. -439 B. -141 C. 153 D. 443
Ulleksa [173]
Answer: Option A -439

(s o t)(x)=s(t(x))
(s o t)(-7)=s(t(-7))
x=-7→t(-7)=3(-7)→t(-7)=-21
(s o t)(-7)=s(t(-7))=s(-21)
x=-21→s(-21)=2-(-21)^2=2-441→s(-21)=-439
(s o t)(-7)=s(t(-7))=s(-21)=-439
Answer: Option A -439

The owner of a video game store creates the expression −2x2 + 24x + 174 to represent the store's weekly profit in dollars, where
Semmy [17]

Answer:

-2(x-6)^2+246, x = $6

Step-by-step explanation:

The expression -2x^2+24x+174 to represent the store's weekly profit in dollars, where x represents the price of a new video game.

Let f(x)=-2x^2+24x+174

We need to rewrite this quadratic function in the vertex form.

f(x)=-2(x^2-12x)+174

f(x)=-2(x^2-12x+36)--2(36)+174

f(x)=-2(x^2-12x+36)+72+174

f(x)=-2(x-6)^2+246

The equivalent expression that reveals the video game price that produces the highest weekly profit  is  -2(x-6)^2+246

and the price is $6
